Off-Road Recovery You may find sometime that your right wheels have dropped off the edge of a road onto the shoulder while you're driving. If the level of the shoulder is only slightly below the pavement, recovery should befairly easy. Ease off the accelerator and then, if there is nothing in the way, steer so that your vehicle straddles the edge of the pavement. You can turn the steering wheel up to 1/4 turn until the right front tire contacts the pavement edge. Then turn your steering wheel to go straight down the roadway. OFF ROAD RECOVERY The fact that such emergency situations are always possible is a good reason to practice defensive driving at all times and wear safety belts properly. edge of paved SUrfBCe
